Description :
The study site is located at Greenwich dunes, Prince Edward Island. This paper focuses on the effects of aeolian transport on surface moisture content rather than moisture as a control on the threshold of aeolian transport. Maps of beach surface moisture were created based on a calibrated relationship between surface brightness from the photographs and surface moisture content measured in situ at points spaced every 2.5 m along a transect using a Delta-T moisture probe. Remote sensing systems such as the one presented here allow observations of the combined evolution of beach surface moisture, shoreline position, and fetch distances during short-term experiments and hence provide a comprehensive rendering of sediment erosion and transport processes.
